UNITED STATES PATENT OFFICE 6 Claims.

This invention relates to detachable window structures of the type wherein the window sashes Vare readily detachable from the window frame and the sashes are frictonally held iniany desired position of adjustment without the use of counter-balancing sash weights.

An object of my invention is to provide a novel and improved guide structure supporting and guiding a window sash for adjustable movement along a window frame, and so arranged that the sash may readily be removed from the frame in a simple operation.

A further object of my invention is to provide an improved structure'and arrangement for guiding a window sash for movement along a window frame wherein the window sash may be positively and detachably locked for sliding move-ment along the window frame, or may readily be removed from the frame for cleaning or repair in a simple operation.

A further object of my invention is to provide a weightless window sash and frame wherein the parting strip dividing the jamb of theframe into the guideways for the upper and lower sashes is yieldable and expansible, to hold the sash in any desired position along the frame.

Still another object of my invention is to provide a detachable sash and window frame structure wherein the sash is detachably mounted on metallic slides slidably guided for movement along the jambs of the window frame and wherein yieldable parting strips are provided between the sashes, yieldably engaging the metal slides to hold the sashes in any desired position along the frame, and act as weather stripping, to seal the Window against the weather.

'I'hese and other objects of my invention will appear from time to time as the following 'specification proceeds and with reference to the accompanying drawings wherein:

Figure 1 is a View in front elevation of a window having sliding upper and lower sashes slidably guided in and held in position in the window frame in accordance with my invention;

Figure 2 is an enlarged fragmentary view in front elevation of a window sash and frame, with certain parts of the sash and frame broken away and shown in section in order to more clearly illustrate certain detailed features of my invention;

Figure 3 is a view in front elevation of the sash and frame somewhat similar to Figure 2, but showing the sash in position to be removed from the frame;

Figure 4 is a horizontal sectional view taken substantially along line IV-IV of Figure 2;

Figure 5 is an enlarged fragmentary sectional view taken substantially along line V-V of Figure 1; and

Figure 6 is a horizontal sectional view taken through the window sash showing the sash in position to be'removed or inserted within its supporting slides,

In Figures 1 and 5 of the drawings, a window frame is shown, which may comprise a lower sill I0, a top head rail H and parallel spaced jambs I2, I2 having guideways I3 and I4 extending vertically therealong.

The guideways I3 and I4 may be formed by the usual blind stops I 5, I5 extending along the outer side of the window frame inwardly from the jambs thereof, and inner headings or moldings I6, I6 extending along the inner sides of the jambs as in Figures 5 and 6. The space between the guide strips I5 and I6 is divided by a central parting strip I I extending vertically along the window jamb and herein shown as being recessed therein.

The parting strip I1 has an outer face recessed in the general form of a V, within which may extend the web of a resilient channel member I9, the legs of which extend along opposite sides of said parting strip.

The channel member IS may be made from a yieldable metal such as steel, aluminum, bronze or brass stripping, and may extend for the entire length of the window jamb, and be drilled along its length to receive screws 26, 20. The screws 20, 20 may be wood screws, which when threaded within the strip I'I and tightened, will recess the web of said channel within the V-shaped recess of said parting. strip. This will flex the legs of said channel, outwardly and yieldably engage said legs with the adjacent legs of generally channel shaped slide members 2 I, 2l. The channel shaped slide members 2|, 2| may .be made from metal, such as steel or aluminum, or any other suitable metal and are slidably guided within the slides I3 and I4 to retain the window sashes therein. As the screws 2D, 2l! are tightened, the legs of the channels i9, I9 flexing against the legs of the channel slide members 2l, 2l will hold said channel slidey members in position along vthe window frame, and will also act as weather stripping and prevent the leakage of air past the sashes. The channel slide members ZI, ZI form detachable slides for upper and lower sashes 23 and 24 respectively, slidably guiding saidsashes in the guideways I3 and I4 of the window frame, as will hereinafter more clearly appear as this specication proceeds. Each window sash is of a similar construction and the detachable mounting of each sash in the channel slide members 2|, 2| is the same so a description of one will sumce for both.

The sash 24 has side rails 25, 25 connected together by top and bottom rails 2B and 21 respectively. The outer side edges of the side rails 25, 25 are spaced inwardly of the inner edges of the jambs I2, I2 when the sash is in position in the frame andiengage inturnedends 28', 2.8 of legs 29; 29`-of"the channel slide members 2|, 2|, when in position in the Window frame, and slidably move along the inturned ends of said legs when being placed in positionV in.. the

frame, as shown in Figure 6.

Each side rail 25 also has a groove 382extending.-

longitudinally therealong and' opening` to the outer side thereof.

of the channel slide member 2|, said leg 33 abutthe outerside. of', the windowl frame atzts inside and the nexibleleg.of-,thepartingiehannel I9 at its outer side.

The sash islocated at--its bottom on theobanncl slide` members 2| .2| for` movement therewith i on upwardly projectinglocatngpins.34 V3de Said pins extend upwardly from the inwardly. extending horizontal legs of. anglesA 35., 35 the.verticlzallegs of. which areV suitably. secured .to the insides .offthe webs ofthechannel-slide members 24,21 as by riveting. Theibottom of-eachfsiderail 25 and the adjacent end portions of eachvbottom ra-il.2 'l are recessed as .indicated lay-reference character` 3l, toreceive the horizontal` leg of the'angle 35-and recess said angle abovethe bottom ofthe window sash. A recess or locating` hole 39,- which may-be lined with=meta1, opens into the recess 31 and conformsgenerally to. the-.diameter ofthe pin-34 and .is providedin eachv side.. rail25v` for` engagement with .the pin 34, to locateV and4 detachably secure theebottom of the rail-25` to its associated channel slide member 2|. A stop 40 at.Y the bottomeftheslide .I4 engagesthe bottom ofthe horizontal leg otzthe angle-,35, .to limit downward movement thereof.

A-lockng plate` 4| is transversely pivoted on the upper end of the web of the channely slide memberZl, to lock the channel `to its associated slidemember. As herein shown, the` locking plateA 4| 1 is .pivotallymovable into.v engagement with theftop of-thewindowsash :and is shown. as being onestrap of a hinge member 43, .theother stron oi which extends-alone "and is `suitable See cured tothe insideortheweb of the-:channel slide ymemberll as by* rivetingl (see-Figuresz and). The locking plate 4-| isishovm as .having an. elongated. slot t5:` adjacent. its:l outerend through which may extend a head 4&1 ofalockinglscrew. The locking screw-isherein; shown.. as being Athreaded in. a 1 metallicA insert 49=threaded within the Vtop rail 2.6-of the sash.. TheheadM of'zsaidlooking screwA is shown as `beingV eccentric of the center of said screw, tot iit within the .slot 45 when. the lockingplate is moved. into engagement with the top of the side rail'Z- and the top rail 26.V Thehead 46 may then be turned, as by ascrewdr'ver, to engage the topv oi'thelocking plate 4l and. positively lock the sash'inposition' on. its associated channel s ldemember 2|. It should here be notedthatthe top ofthe side rail, 25 and the topV rail 26'isrecessed'to recess the locking plate 4| beneath the top ofthe window sash, to .accommodate the window'toopen or' close all the way. It should also be notedthat while asorew havingzan eccentric head is Shown.'

The groove 30' is adapted to register with an inturned end 3| ofi a: leg331' 4. any other suitable locking means may be used instead.

When it is desired to place the sash in position in the Window frame, assuming the channel slides 2|, 2| are in place in the window frame as in Figure 6, the locking plates 4|, 4I may be pivoted upwardly. The sash may then be slidably moved inwardly along the inturned ends 28, 2B of the legs 29, 23 of the channel slide members 2|, 2| ata sulicient elevationto clear-the tops of the locating'pins 34'; 34 until the inturned" ends 3|, 3| of the outer legs 33, 33 come into engagement with the slots 30, 30 and the outsides of the rails 25,425 engagethe insides of said legs. The sash may then be moved downwardly along the slide membersl; 2| to engage the locating pins 34, 34 with the recesses 39, 39 and engage the bottoms of'tlie slots 3l, 31 with the horizontal legs ofi the; angles 35, 35. The locking plates 25, 25 may then be pivoted downwardly into the recessedportions of the top -of the-sash over the eccentric4 heads Mi,- 46.- of` the locking. screws. Saidscrews-mayf thenbe turned to engage the undrsides of the heads thereof with the topsvof the .locking plates 4| 4| and positively lock the sash in position in the window frame.V Thefsash may then be freely moved. along the window frame on the channel sliding membersgZl; 2| movable along their respectiveguideways.- y

It is understood that thelegs of the ilexble channels I9, I9 engaging .thelegs -of the channel slide members 2|, 2| may yieldably holdlthesash in position in the frame at anyfdesiredposition andthat the screws 20, .2B may be tightened .to engage the legs of the nexiblecliannels I9, 1 9 with the adjacentlegs of the slide membersfZt, 2| with suiiicient force to positively lockthe sash from movement along the frame, if desired-V Whenl it is desired to remove the sash `from-the window frame for cleaning or repairing, it isonly necessary to turn one lookingiscrew soitsffhead 48. will pass through the slot 45; The locking plate may then be` pivoted upwardly' andi the entire sash mayA be slidably moved' upwardly alongthe associated channel sliding member 2| until the pin 34 is disengaged from the;Y aber'. ture 3.9. The sash may then beswungoutwardly about the opposite channel slide and. removedfrom the window withV one slide securedthereto. It is, of course, obvious thatif desired, bothJlockingv plates may be unlockedfrom thesash, and the sash may then be. movedl upwardlyA along both channel slides and then-bodily removed therefrom.l

Itmay be seenfromthe foregoing. theta4 simplied form of detachablewindow sash'has been provided, which freely slides along-f the slides, inthe Window jambs` and-yetmay bell-leid' in anyfdesired position -withfrespectto the lamb; and be removed fron'rori replacedinithe'fjamb' by a. simple unlocking; slidingA and" pushing or pulling operation, rendering it extremely'simiy ple to take outV the window' sash` forfcleanin'g both sides thereof, or for painting-or repairing.'
